On one description of the continental bills of credit, issued by congress during the American war, were represented a sundial and a meridian sun over it: above, the word “Fugio;” and beneath, these words—“Mind your Business.” And on the reverse of a copper one cent piece, struck in the year 1787, in pursuance of a resolve of congress of the 6th of July in that year, are impressed the same device and mottoes as those last mentioned; corresponding with those adopted by our Philosopher, when only twenty-four years of age: a circumstance that shews, how early in life he had formed a just estimate of the value of time. It may not be improper here to observe, that the various devices affixed to the continental money, as it was called, were much admired for their appropriate significancy; and that they were generally supposed to be the production of the late ingenious Judge Hopkinson, an intimate friend of Mr. Rittenhouse. ----- Though rather plain and simple than otherwise, in all his domestic arrangements, he lived well,—in the common acceptation of the phrase. Nor was he in any respect deficient in that decorum in his personal appearance, and in the modest appendages of his household, which corresponded with his character and station in society. There was not the least affectation of any thing like parade or splendour, in his manner of living. In his dress he was remarkably neat, correct and gentlemanlike: his house, with its furniture were of a corresponding style of propriety; the mansion itself, with every thing appurtenant to it, seemed to denote its being the residence of good sense, elegant simplicity, and genuine comfort.
